To concern the technical or experimental feasibility, we also numerically show that the indirect measurement based on the Jaynes-Cummings model[1]} can nearly achieve the Helstrom bound between binary NS-CS. This implies that the indirect measurement can perform the quantum communication enhanced by the binary NS-CS. Whereas Dolinar-like receivers need real-time electric feedback, our indirect measurement does not. In other words, it is possibly easier to implement our indirect measurement than Dolinar-like receivers. As the experimental implentation of ultrastrong Jaynes-Cummings model is still actively studied[2]}, the indirect measurement considered in this article can be expected to be implemented in the near future.
